HORACE BRAINERD CAMP, OF AKRON, OHIO:

CLUTCH-OPERATING DEVICE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed December 19,1906. Barium- 348,582.

To all whom it may concem:

Be it known that I, Henson BRAINERD CAMP, a citizen of the UnitedStates, residing at Akron, in the county of Summit and State of Ohio,have invented new and useful Improvements in Clutch-Operating Devices,of which the following is a specification.

This invention relates to power devices for operating clutches andsimilar mechanisms, and the object thereof is to provide a simple andeffectual device which may be utilized to operate clutches and likeinstrumentalities where the power required is too great for manualoperation, or the position of the device to be operated is such that itcannot be readily reached.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement o'f partsconstituting the invention to be hereinafter referred to and illustratedin the accompanying drawings which form a part of this specification inwhich is shown the preferred'cmbodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

In the drawings, in which similar reference numerals indicate like partsin thedifierent figures: Figure 1 is a side elevation of my improveddevice in connection with a friction clutch; Fig. 2 is a longitudinalsectional view of the valve employed in this device; Fig. 3 is a plan ofthis device with a portion thereof in section to better illustrate theconstruction thereof; and, Fig. 4 is an end elevation looking from theright of Fig. 1. i

In the description hereinafter given, the adaptability of my device forthe operation of clutches will be used as a means for illustrating theconstruction and operation thereof.

In the drawings, the reference numeral 1 designates a shaft from whichit is desired to communicate power to some other mechanism. On thisshaft is mounted a clutch of any preferred type, designated in thedrawings by the reference numeral 2, the loose member of which issecured to a pulley 3. A belt may be used to transfer power from thispulley 3 to any other mechanism. The mechanism of the clutch isconnected lars 7. Projecting from opposite sides of the member oppositeends of the cylinders 9 are closed by heads 10. These heads 10 are heldin position by bolts 11 passing through both the heads 10 and brackets 8and provided on the outside thereof with nuts 12. Through the heads 10are piston rods 13 provided with ordinary stuffing boxes 14 and bearingon their inner ends within the cylinder 9, pistons 15. These piston rods13 are connected at their outer ends to a yoke 16 which incloses theflanged end 5 of the sleeve 4 so that any motion communicated to thepistons 15 will cause a corresponding motion of the sleeve 4 whichoperates the clutch. Any suitable fluid may be used for operating thesepistons and it is conveyed thereto and withdrawn therefrom through thefollowing arrangement of pipes: From suitable openings in the brackets 8extend pipes 17 which are connected to a single pipe 18, from which, byany suitable arrangement of pipes, extends a pipe 19. From suitable.openings in the heads 10 extend a similar system of pipes, designatedin the drawings by the reference numeral 20 and eventually uniting in acommon pipe 21. Connected with the pipes 19 and 21 and referred togenerally by the reference numeral 22 is a valve. This valve, shown inlongitu dinal section in Fig. 2, consists of a central piston 23provided with a narrowed central portion 24, and fur-' ther providedwith a stem 25, and knob 26 for manipu; lation. The casing of this valveconsists of a-cylinder 27 having four openings 28, 29, 30 and 31. Theopenings 28 and 29 are connected to the pipes 19 and 21 respectively.The opening 30 constitutes the exhaust and is preferably provided withan outlet pipe 32.

The opening 31 is the inlet and is provided with a pipe 33. When thepiston 27 is in the position shown in Fig. 2,- the ports 28 and 29 areclosed. If the piston is moved to the right the fluid from the inlet 31can pass around the reduced portion 24 to the port 29 and from thence bythe pipes already described to the rear portions of the cylinders 9. Ifthe piston 23 is moved to the left the fluid from the inlet 31 will passin the same manner to the port 28, and the exhaust from the cylinderswill pass through the port 29 into the cavity of the casing 27 andthrough the interior of the piston 23 to the exhaust 30. It will beobvious that when the piston 23 is moved to the right the exhaust fromthe port 28 will pass around the end of the piston and escape throughthe exhaust 30. In order to prevent the revolution of the member 6 withthe shaft 1 there is formed thereon an integral lug 34 to which issecured a bar 35 attached to some fixed object such as a beam or post,referred to in the drawings by the reference numeral 36. v

It will be seen from the foregoing description that by a very slighteffort in operating the valve 22, movement of the pistons and theirconnected mechanism may be accomplished and this will produce an opera.-

tive force on the clutch-operating mechanism, comthereto.

What I claim and desire to secure by Letters Patent,

1. The combination in a device of the class described, of a shaft, aclutch mounted thereon, a sustaining member inc-losing said shaft andsupported thereby, means to prevent longitudinal movement of saidmember, means to prevent the revolution of said member in unison withsaid shaft, a plurality of cylinders supported-by said member, pistonrods arranged to be operated by said cylinders connected to theclutch-operating mechanism, and means to control a supply of fluid tosaid cylinder.

2. The combination in a device of 'the class named, of a shaft, a clutchmounted thereon, a sustaining member mounted on and inclpsiqg saidshaft, means for preventing rotary and iongitudihiii riovement of saidmember, said member being provided with extending brackets havingroccsses therein, cylinder bodies mounted in said recesses, heads forsaid cylinders, means for clamping said heads on said cylinders and saidcylinders in said recesses, piston rods in said cylinders attached tothe clutch-operating mechanism,'and means to control a supply of fluidto said cylinders whereby said piston rods may be reciprocated tooperate said clutch.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
